Stop re-explaining your company in every chat: write a one-page brief about your business (what you sell, who your customers are, your tone, your goals) and put it where the AI can always see it. In ChatGPT that means custom instructions plus Projects with your key docs uploaded; in Claude, Projects with a knowledge base works the same way; memory then picks up preferences over time automatically. Once the context lives in the tool instead of in your prompts, every answer starts from 'knows my business' instead of 'generic advice'.
